1. A method, performed by a base station, of providing synchronization signal block indication information in a wireless communication system, the method comprising:
configuring the synchronization signal block indication information, based on information regarding an uplink-downlink slot configuration and a ratio between a subcarrier spacing at which the synchronization signal block is transmitted and a subcarrier spacing to which the uplink-downlink slot configuration is allocated;
transmitting the configured synchronization signal block indication information to a terminal; and
transmitting at least one synchronization signal block, based on the configured synchronization signal block indication information,
wherein a plurality of synchronization signal blocks to be transmitted in a full frame are divided into at least one group, based on the ratio between the subcarrier spacing at which the synchronization signal block is transmitted in the full frame and the subcarrier spacing to which the uplink-downlink slot configuration is allocated,
wherein the plurality of synchronization signal blocks to be transmitted in a half frame are divided into the at least one group, based on a repetition period of the uplink-downlink slot configuration and a repetition period of a pattern of a slot in which the at least one synchronization signal block is transmitted in the full frame, and
wherein the synchronization signal block indication information includes a first type information bit indicating whether each of the at least one group is transmitted and a second type information bit indicating whether synchronization signal blocks corresponding to each of the at least one group is transmitted.
